SELF-CLOSING FAUCET.

SPECIFICATION forming part of Letters Patent No. 549,355, dated November 5, 1895.

Application filed January .16, 1895- Serial No. 535,134. (N0 modeL}.

T0 aZZ whom zjt may concern.-

Be it known that I, JAMES J. GANNON, of New York city, in the county and State of New York, have invented a new and Improved Self-Closing Faucet, of which the following is a full, clear, and exact description.

My invention relates to improvements in self-closing faucets; and the object of my invention is to produce a simple and inexpensive faucet which is self-closing, which also has its valve pressed normally into closed position by the pressure of liquid within the faucet, and which has a very simple cam mechanism for moving the valve against the tension of its spring and thus opening the faucet.

To these ends my invention consists of certain features of construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the faucet with the working parts shown in section. Fig. 2 is a sectional plan on the line 2 2 of Fig. 1, and Fig. 3 is a detail inverted plan of the fork and bearing-balls used to depress the cam-ring and open the faucet.

The faucet is provided with an elongated barrel 10, from which leads a discharge-spout 11, and the faucet near the bottom has a collar 12, adapted to rest against any ordinary abutment, while the extreme lower end of the faucet is screw-threaded, as shown at 13, to enable a coupling to be easily effected between the faucet and an ordinary supply-pipe 14. All the above construction is common to faucets of this class.

The faucet has within it a longitudinallymovable valve-stem 15, which, near its lower end, is fluted, as shown at 16, in order that water or other liquid may travel through the flutes of the stem, and the stem extends through a port 17in a transverse partition 18 of the faucet, which partition has its under side formed into a seat against which the valve 19 presses, this valve being secured to the lower end of the stem. The stem extends through a guide partition 21 above the discharge spout, and it is pressed by a spring 20, so as to hold the valve 19 firmly against its seat. The spring 20 is coiled around the valve stem above the partition 21 and it presses against the top of the cam-ring 22, which is slidable longitudinally in the barrel 10 and which has side ribs 23, (see Fig. 2,) which run in grooves 24 in the inner wall of the barrel 10 to prevent the cam-ring from turning. The cam-ring 22 has at the top and on opposite'sides cams 25, on the inclined faces of which ride the balls 26, which are socketed in the ends of the fork 27, and the fork is secured to the inner end of a handle 28, this being journaled in the cap 29, which is screwed to the upper or outer end of the barrel.

The handle 28 has a collar 28, which presses against the inner side of the cap 29 and prevents the handle from slipping out, and when the handle is turned the balls 26, riding on the inclined faces of the cams 25, cause the cam and cam-ring to be depressed, and the ring carries with it the valve-stem 15 and so pushes the valve 19 from its seat, and the water or other liquid may then flow through the port 17 and out through the dischargespout 11.

In order that the spring and the mechanism in the faucet-top may be protected from liquid, a gasket 30 is placed upon the stem 15, and it fits snugly beneath a collar 31 on the stem. It will be seen that by turning the handle 28 the fork 27 will actuate the cams 25 and open the valve 19; also that the arrangement of the balls 26 in the fork is such as to insure easy action and great durability. It will be seen, further, that the pressure of the spring 20 will keep the valve 19 closed, and that this action is facilitated by the pressure of liquid against the valve.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of the casing, the valve therein, the spring-pressed stem secured to the valve and provided with. a cam at its end, and the forked handle mounted to turn in the casing and provided in its ends with sockets for the reception of bearing balls adapted to ride on the cam, substantially as described.
